Answer to first question yes!!!!_______________________________________________________________It only takes 4 bursts if aimed directly 3 to take down the shield and 1 to kill!!!_______________________________________________________________Rank: Senior Chief Petty Officer Franklin Mendez

Description: He was the Spartan II training leader when on Reach in 2517 til 2525. He trained them as hard as any Marine when they were only 6.

He had won numerous rewards including multiple Silver Stars, Bronze Stars, three Purple Hearts and The Red Legion of Honor. In the beginning of their training Mendez and his instructors had to use Electric Batons. Eventually the Spartans looked up to Mendez as a unmovable force in their life. They had great respect for him.

After their training was completed he was reassigned to train the next class of Spartans II though he wasn't heard of for some time. Most assumed he was dead along with any Spartans he may have been training when Reach fell.

Mendez requested reassignment to active duty. Over the next six years he fought the Covenant on five worlds won two more Purple Hearts and was promoted to Senior Chief Petty Officer. Mendez was recruited by Colonel James Ackerson to assist Spartan 051 in running the Spartan III program. He trained Spartan III at Camp Currahee on planet Onyx from 2531 until 2552.

Mendez was on the planet when Onyx was activated. He with Spartan III Team Saber were alone on the planet and hid from the Sentinels until Kelly 087 and Dr Halsey arrived, then Fred 104, Will 043 and Linda 058. Mendez helped them fight all the way to the core of Onyx. Mendez then went to Shield World along with the other survivors!!!

Wow...I would SERIOUSLY think that more people played Halo on this site....

I think they do it's just your questions are a little too hard and confusing for those like myself who are just 'average fans'. You may consider dumbing down your questions...it's what I did with the KotOR quiz.
